P. WARNICK WINDOW SCREEN April 29, 1930.

This invention relates to window screens and more particularly to devices for holding the edges of window screens tightly against a window frame.

There is now in general use, a window' screen which may be wound upon a roller, when not in use, in the same manner as a window shade. However, such screens, on account of their mounting and construction, have their side edges free, and as a result flies, bugs and other insects, are able to pass freely around the edges of the screen, there being an appreciable space between the screen and the window frame, and consequently are objectionable in that respect.

It is an ob'ect of this invention to provide a device for tightly clamping the side edges of a screen, of the type described, against a window frame so that there will be no openings available for the entrance of insects and other undesirablethings which the screen is intended to exclude.

A. further object is to provide a clamping device which will occupy an inappreciable space so that it will not change the appearance and structure of the window.

These and other objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown'in. the accompanying drawing, constituting a material part of this disclosure, and in which:

Figure 1 represents a vertical sectional view of a window equipped with my clamping device.

Figure 2 represents a perspective view showing details of my improved clamping device, part of the handle being broken away.

Figure 3 represents a transverse sectional view taken on line 3-3 of Figure 1.

Figure 4: represents a" transverse sectional view taken on line 4-4 of Figure 1.

Figure 5 represents a transverse sectional view taken on line 5-5 of Figure 1, and shows, in addition, the full body portion of the handle and easing of my improved clamping device.

My improved clamping device consists essentially of the stationary plate 5, provided with a flange 6 and lugs 7 and 8, engaging 1929. Serial No. 357,382. I

with the edges 8rof apertures 9 in the movable flanged plate 10, the flanged plate 10 being provided with lugs 11 engaging, the edges 12' of apertures 13 in the clamping strip 1%; r v Y The clamping strip 14:, whose flange 15 engages the flange 1 6 of movable plate 10, is. movable longitudinally on that plate bymeans of connecting links 17 which are pivoted at 18 to the clamping strip 14, and at the '60- other end at 18, to the stationary plate 5. An operating crank 19 is securedto one of the links, preferably by engagement of the square portion 20 of the crank with a square aperture'21 in the link. .The lower end 22 of the crank is revolvably secured in the stationary plate 5, and the upper end 23 serving as a handle, projects through the casing 24: which conceals the partsof the device. The

'device is secured to the window'fram'e in any l0 suitable manner.

As shown in Figure 1, the screen 25, whose side 7 edges are preferably held between felt se-ipgmt shown,is wound'on a roller27 in a box 28 in which an additional roller carry-' ing ashade 29;is mounted, the screen and shade pressing through slots 30 and 31,respectively, in the bottom of the box 28.

In operation, when the'screenhas been moved to the desired position between the '30 flanges 6 and 16, the links 17 are moved in a counter-clockwise direction, (see Figure 1), to cause the strip 14 to move longitudinally downward on movable strip 10. Since'the lugs 11 prevent transverse movement of strip 14 relative to movable plate 10, the latter is moved transversely, longitudinal movement of movable strip 10, being prevented by the lugs 7 and 8 on plate 5. The lateral movement of plate 10 causes flange 16 to come into clamping engagement with flange 6 and clamp the side edges of the screen'therebetween. j

To release the screen the links 17 are r0- tated in the opposite direction until they asi sume the position such as shown in Figure 1. The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention,

of which obviously an embodiment may be v 2: r s 1,756,496 r constructed including many modifications without departing from the general scope herein indicated and denoted in the appended claims.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is: v

1. A device for clamping the sideedges of a window screen comprising a stationary plate provided with a flange, a movable plate provided with a flange, a link pivoted'onisaid stationary plate, means pivotally connected with said link to bear against-the movable plate to cause'the latter to move laterally 15 when said link is rotated; 2. A device for clamping the side edges of a window screen comprising a stationary plate having a flange, a movable plate having a flange,'a strip slidably mounted on said vg3, movable plate, means to prevent lateral movement of said strip relative-to the movable plate, means to prevent longitudinal movement of the movable plate relative to the stationary plate, and a link pivotally connected $5 to the strip and to the stationary plate, rotation of said .link causing said movable plate to move laterally to vary the relative position of the flanges on said plates.

3. A device for clamping the side edges of a window screen comprising. a stationary plate having a flange, a movable plate having a flange, means to prevent longitudinal movement ofsaid movable plate relative to the stationary plate, a strip slidably mounted onsaid movableplate, means to preventflateral movement of said strip relative to'the movable plate, and a link pivotally connected to the strip and to the stationary p1atewhereby rotation of saidlink will cause said movable plate to move'laterally.

4. In a device for clamping the side edges 7 of a window screen, comprising arstationary, plate provided with a flange,'a'movab1e plate provided with a flange adapted to be moved into clamping engagement with the flange on the stationary plate, means to prevent longi tudinal movement of said movable plate, a strip slidably mounted on said movable plate, lugs projecting from the movable plate and 50 engaging said strip to restrict the latter to longitudinal movement relative to said movable plate, a link pivoted to the strip and tothe stationaryrplate, and a crank connected to the link ,to rotate the latter to cause the v 55 movable plate to be moved laterally.
